Question

Answer both A and B please

Answer 1

Answer: a. when x=0, the value of the function is 3

b. when x=5, the value of the function is -10

Explanation:

`\displaystyle\\y=\left \{ {{(3)/(2)x+3,\ if\ x\leq 0 } \atop {-2x,\ if\ x > 0}} \right.`

`\displaystyle\\x=0\\\\Hence,\\\\y=(3)/(2) (0)+3\\\\y=0+3\\\\y=3`

`x=5\\\\Hence,\\\\y=-2(5)\\\\y=-10`

Answer 2

3 and - 10

Explanation:

(a)

when x = 0 in the interval x ≤ 0 then y =
`(3)/(2)` x + 3 , so

y =
`(3)/(2)` (0) + 3 = 0 + 3 = 3

when x = 0, the value of the function is 3

(b)

when x = 5 in the interval x > 0 then y = - 2x , so

y = - 2(5) = - 10

when x = 5 the value of the function is - 10
